1. A power device configured to provide power to a medical device, comprising:
(a) a housing configured to removably couple with a medical device;
(b) a power assembly supported by the housing, wherein the power assembly includes a rechargeable battery pack and a power sensing circuit, wherein the power sensing circuit is configured to modulate a power output of the rechargeable battery pack to maintain an output signal;
(c) an electrical connection feature operable to electrically couple with a complementary connection feature of the medical device, wherein the electrical connection feature is operable to deliver the output signal from the rechargeable battery pack to the medical device, wherein the electrical connection feature is further operable to receive a return signal from the medical device; and
(d) a processor configured to:
(i) receive the return signal,
(ii) determine whether the output signal is sufficient to power the medical device based at least in part on an electrical characteristic of the output signal or the return signal, and
(iii) adjust a voltage of the output signal so that the output signal is sufficient to power the medical device.
